IPC: B67D7/40
Filed: 1990-03-16
Abstract: PURPOSE:To mount a hose container by using an existing unit without modifying by coaxially arranging a fuel hose and a vapor recovering hose in combination, and employing a bellowlike extensible/contractible hose as the recovering hose. CONSTITUTION:A hose container 1 of a suspension type refueling apparatus is provided at a high place, a vapor recovering hose 2 suspended from the lower part of the container 1 and an inner fuel hose 3 are shown, and a vapor recovering nozzle 4 is integrally provided at the end of the hose to refuel a vehicle 6. In this case, the bellowlike part of the hose 2 is elongated. Vapor is passed through a vapor passage 6 during charging of fuel from the nozzle 4 into the vehicle 5, fed to the container 1, and recovered to a predetermined vessel through a recovery tube 8. When charging of the fuel is finished, the hose 3 is wound by a hose winding unit 7 in the container 1. In this case, the hose 3 is contracted. That is, since it is extensible and contractible, the recovering hose may not be wound. Since hermetical seal is held by a sealing packing 9 between the hose 3 and the hose 2, the vapor recovered externally is not leaked.

Title: Engaging implement
Inventor: MORITA TAMAO
IPC: H01F7/02
Filed: 1990-03-20
Abstract: PURPOSE:To be scarcely separated even if an attracting tool and a tool to be attracted are pulled in a separating direction by providing an overhang collar at a ferromagnetic protrusion of the tool to be attracted, forming the hole of a permanent magnet of the attracting tool of a deformation hole having small and large diameter parts of a pole side, and providing an overhang collar inserting gap of the protrusion at the periphery of the small diameter part side. CONSTITUTION:When mounting members of an engaging implement are pulled in a separating direction, if a ferromagnetic protrusion 3a of a tool to be attracted is so mounted as to be engaged with the small diameter part 3a' side of a hole 1a of an attracting tool A, even if a separating force of the tools A, B is acted at the members, an overhang collar 3a is engaged with an inserting gap 4, and not removed. Since a gap (s) is provided between the protrusion 3a and a ferromagnetic plate 2 or the protrusion 2a at the time of engaging the tool B with the tool A, the size of the protrusion 3a may not be precise. Since lines of magnetic force bridge the gap (s) to form a magnetic circuit, its attracting effect is large.

Title: Noise eliminating device
Inventor: KANBA SUSUMU
IPC: H04M1/60
Filed: 1994-04-06
Abstract: PURPOSE:To keep the speech quality without suppressing useful acoustic noise by eliminating an acoustic noise at a high noise elimination capability when the acoustic noise is not in steady-state and eliminating or stopping the acoustic noise at a weak noise elimination capability when the acoustic noise is in steady-state. CONSTITUTION:When an acoustic noise is discriminated to be not in steady-state for a long time, a control section 104 controls a noise canceller 105 in a way that the canceller 105 eliminates noise by using a newest parameter among parameters extracted when the acoustic noise is discriminated to be in a steady- state for a long time for a period discriminated to be a non-voice state. However, the control section 104 controls the noise canceller 105 to use weak noise capability. The noise eliminating capability is positively reduced, because the noise discriminated to be in the non-steady-state for a long time is substantially a long time non-steady state noise or a noise in the non-steady-state noise superimposed on the steady-state noise, and in the former case, the deterioration in the signal quality is relaxed.
